Description

Technical Field

[0001] This invention relates to the field of soil sampling device technology, and in particular to a portable field rhizosphere soil sampling device. Background Technology

[0002] Rhizosphere soil, as a key area for the interaction between plant roots and soil microorganisms, has significant implications for plant growth, nutrient absorption, and stress resistance due to its physicochemical properties and microbial community structure. In agricultural research and production practice, rapid and accurate collection of rhizosphere soil samples is a prerequisite for conducting related studies. Current rhizosphere soil sampling methods require manual sieving after excavation, which is cumbersome, inefficient, prone to damaging the original soil structure, and results in incomplete impurity removal. Some portable sampling devices are complex in structure, lack portability, and are difficult to adapt to the needs of multi-site sampling in the field. Therefore, developing a lightweight device that is easy to operate in the field and can quickly separate impurities and collect rhizosphere soil samples is of great significance for advancing agricultural soil research.
